End member-to-member access
Use Block When You Need Contact to Stop
Current EliteSingles help says Block stops further communication from that member and prevents them from viewing your profile. The same help text also mentions preventing comments on your blog posts, although that feature may not appear in every current account view.
The blocked member is not notified. Current instructions place unblocking under Settings → Blocked Members. Treat that path as the documented route and follow the wording shown in your account if the menu has changed.
Unblocking restores only the access the product currently supports. It does not promise that earlier messages, likes or recommendations will return.
